[0035] Reference Figure 1 , a cabinet door interlock device in the present application includes a cabinet 100, a door panel 110, a linkage structure 120 and a door lock 130. As shown in the figure, the door panel 110 has an upper side, a lower side, a first side 111 hinged to the cabinet 100, and a second side 112 opposite to the first side 111. The door panel 110 is used to rotate relative to the cabinet 100 with the first side 111 as a rotating shaft to open or close the door opening of the cabinet 100; the linkage structure 120 includes a linkage rod 121 and a plurality of first lock pins 122, the upper side and / or the lower side is a locking side, the linkage rod 121 is movably arranged on the locking side, one of the linkage rod 121 and the cabinet 100 is provided with a first lock pin 122, and the other is correspondingly provided with a first card slot 210, the first card slot 210 includes a first sub-slot 211 and a second sub-slot 212, and the first sub-slot 211 and the second sub-slot 212 are connected. The sub-grooves 212 are staggered to form an L-shape, and a first opening is formed at one end of the first sub-groove 211 away from the second sub-groove 212, and the first opening is used for the first lock pin 122 to enter or leave the first card slot 210; the door lock 130 is arranged on the door panel 110, and the door lock 130 can move relative to the door panel 110 to lock or unlock the second side 112 of the door panel 110 with the cabinet 100, wherein the linkage rod 121 is transmission-connected to the door lock 130, and when the door lock 130 reaches the locked position, the linkage rod 121 is driven by the door lock 130 to make the first lock pin 122 reach a position in the second sub-groove 212 that is misaligned with the first sub-groove 211, and when the door lock 130 reaches the unlocked position, the linkage rod 121 is driven by the door lock 130 to make the first lock pin 122 reach a position in the second sub-groove 212 that is opposite to the first sub-groove 211.

[0036] Specifically, the linkage rod 121 extends along the locking edge of the door panel 110, and can be driven by the door lock 130 to move back and forth along the locking edge, so that the first lock pin 122 can slide back and forth along the second sub-groove 212. The first sub-groove 211 and the second sub-groove 212 are staggered to form an L-shaped first card slot 210, which facilitates the snap connection and unlocking between the first lock pin 122 and the first card slot 210. The first lock pin 122 of the present application is set on the linkage rod 121, and the first card slot 210 is set on the cabinet 100. The opening direction of the first opening of the first sub-groove 211 is outward relative to the cabinet 100. Figure 2 When the door panel 110 rotates relative to the cabinet body 100 and closes the cabinet body 100, so that the first lock pin 122 passes through the first opening into the first sub-groove 211 and faces the second sub-groove 212, the door lock 130 is adjusted to the locking position, and the linkage rod 121 is driven by the door lock 130 to move along the locking edge, driving the first lock pin 122 to move deeper along the second sub-groove 212 in a direction away from the first sub-groove 211, so that the first lock pin 122 reaches a position in the second sub-groove 212 that is misaligned with the first sub-groove 211, so that the first lock pin 122 is buckled into the first slot 210, thereby achieving the locking of the locking edge of the door panel 110 and the cabinet body 100. Figure 3 When the door lock 130 reaches the unlocking position, the linkage rod 121 is driven by the door lock 130 to move back along the locking edge, driving the first lock pin 122 to slide along the second sub-groove 212 in the direction close to the first sub-groove 211, so that the first lock pin 122 reaches the position where the second sub-groove 212 and the first sub-groove 211 are opposite to each other, thereby achieving the effect of unlocking the first lock pin 122 and the first card slot 210. At this time, the door panel 110 is pulled, and the door panel 110 rotates relative to the cabinet body 100 and opens the cabinet body 100, and the corresponding first lock pin 122 leaves the first opening of the first sub-groove 211, thereby realizing the overall unlocking of the door panel 110.

[0037] The locking edge of the door panel 110 of the present embodiment includes the upper side and the lower side of the door panel 110, and the two linkage structures 120 are respectively arranged along the upper side and the lower side of the door panel 110. The present application adjusts the door lock 130 to move relative to the door panel 110 to enter a locked state or an unlocked state, so that the door lock 130 can drive the linkage rod 121 to move back and forth along the upper side and the lower side of the door panel 110, thereby driving the first lock pin 122 to slide along the second sub-groove 212 until it is buckled into the second sub-groove 212, thereby achieving simultaneous locking of the second side 112 of the door panel 110 with the locking edge, and driving the first lock pin 1 22 slides along the second sub-groove 212 to a position relative to the first sub-groove 211, thereby realizing simultaneous unlocking of the second side 112 and the locking edge of the door panel 110. It can be seen that the door panel 110 can connect and lock the gap between the upper side and the cabinet 100, and between the lower side and the cabinet 100 during the arc burning test, thereby reducing the arc burning from penetrating the weak points of the cabinet 100. Moreover, through the cooperation between the linkage structure 120 and the first card groove 210, the door panel 110 can complete the simultaneous locking or unlocking of the second side 112, the upper side and the lower side of the cabinet 100 only under the activity of the door lock 130, which is convenient for use.

[0038] Further, see Figure 4 The first card slot 210 is arranged on the cabinet 100, the first lock pin 122 is connected to the linkage rod 121, and the linkage rod 121 is provided with an installation slot 410 on one side facing the cabinet 100, and the first lock pin 122 is passed through both sides of the installation slot 410.

[0039] Specifically, the linkage rod 121 provides two support points for the first lock pin 122, reduces the shaking of the first lock pin 122, improves the installation strength and connection stability of the first lock pin 122, and when the first lock pin 122 penetrates the first card slot 210, the edge of the cabinet 100 provided with the first card slot 210 penetrates into the installation slot 410, and the installation slot 410 provides avoidance for the movement of the cabinet 100. The two ends of the first lock pin 122 of this embodiment are respectively penetrated on both sides of the installation slot 410 to provide support for the two ends of the first lock pin 122. In addition, the first lock pin 122 can have only one connection position with the linkage rod 121, and the end or middle of the first lock pin 122 is connected to the linkage rod 121. In this embodiment, a plurality of first lock pins 122 are arranged at intervals along the extension direction of the linkage rod 121, and a plurality of corresponding first card slots 210 are also arranged at intervals along the edge of the cabinet 100, thereby improving the locking stability of the door panel 110 and reducing arcing.

[0040] In some other embodiments, the first lock pin 122 can be set in the cabinet 100, and the corresponding first slot 210 is set on the linkage rod 121. The first opening of the first slot 210 faces the door opening of the cabinet 100. The linkage rod 121 drives the first slot 210 to move back and forth so that the first slot 210 can fasten the first lock pin 122 or disengage the first lock pin 122.

[0041] Further, see Figure 5 Combined with Figure 2 and Figure 3 A guide frame 220 is disposed on the door panel 110 , and a guide slot 510 is disposed on a side of the guide frame 220 facing the cabinet 100 , and the linkage rod 121 is slidably connected in the guide slot 510 .

[0042] Specifically, when the door lock 130 drives the linkage rod 121 to move, the linkage rod 121 can slide back and forth along the guide groove 510, and the guide frame 220 guides the linkage rod 121 to improve the stability of the linkage rod 121. In this embodiment, the extension direction of the guide groove 510 is parallel to the extension direction of the locking edge, which further improves the movement stability of the linkage rod 121 and the locking effect on the locking edge.

[0043] In addition, the side walls of the guide frame 220 are provided with avoidance grooves 520 corresponding to the ends of the plurality of first locking pins 122 , and the extension direction of the avoidance grooves 520 is parallel to the extension direction of the guide through grooves 510 , and the first locking pins 122 extend into the avoidance grooves 520 accordingly.

[0044] Specifically, both ends of the first locking pin 122 pass through the linkage rod 121 and the guide frame 220 respectively. When the linkage rod 121 slides relative to the guide frame 220, the first locking pin 122 can slide smoothly in the avoidance groove 520, further improving the connection strength between the linkage rod 121 and the first locking pin 122 and improving stability.

[0045] Reference Figure 6The door lock component 130 includes a vertical rod 131, and the vertical rod 131 is configured to be able to move back and forth along the second side 112 of the door panel 110. The linkage structure 120 also includes a linkage plate 420, one end of the linkage plate 420 is connected to the vertical rod 131, and the other end is connected to the linkage rod 121. The middle position between the two ends of the linkage plate 420 is rotatably connected to the door panel 110, and the vertical rod 131 moves back and forth along the second side 112 of the door panel 110 to drive the linkage rod 121 to move back and forth along the locking edge; the linkage rod 121 is configured to move back and forth along the locking edge so that the first lock pin 122 moves back and forth in the second sub-groove 212 to switch between a position opposite to the first sub-groove 211 and a position misaligned with the first sub-groove 211.

[0046] Specifically, when the door lock 130 needs to enter the locked state, the vertical rod 131 moves along the second side edge 112 of the door panel 110, driving the linkage plate 420 to rotate, so as to drive the linkage rod 121 through the other end of the linkage plate 420 to engage the first lock pin 122 with the second sub-slot 212, thereby making the first lock pin 122 and the first sub-slot 211 mutually misaligned, thereby achieving the locking of the locking edge and the door panel 110. When the door lock 130 needs to enter the unlocked state, the vertical rod 131 moves along the second side edge 112 of the door panel 110, driving the linkage plate 420 to rotate, so as to lock the first lock pin 122 with the second sub-slot 212 through the other end of the linkage plate 420. The driving linkage rod 121 of the linkage plate 420 unlocks the first lock pin 122 and the second sub-slot 212 from each other, so that the first lock pin 122 can be opposite to the first sub-slot 211, so that the door panel 110 can be rotated to bring the first lock pin 122 out of the first opening, thereby unlocking the locking edge and the door panel 110. In this embodiment, the transmission distance of the door lock 130 to the linkage rod 121 is increased through the transmission connection between the vertical rod 131 and the linkage plate 420, so that the locking of the upper and lower sides of the door panel 110 can be achieved at the same time by adjusting the position of the door lock 130.

[0047] It should be noted that the linkage plate 420 of this embodiment is L-shaped, which facilitates the linkage plate 420 to rotate under force. In addition, the linkage plate 420 can be rod-shaped, triangular, quadrilateral, circular, etc. The door lock 130 can be achieved by providing a buckle structure between the vertical rod 131 and the cabinet 100 to achieve locking between the second side 112 of the door panel 110 and the cabinet 100, or by a latch structure.

[0048] Further, combined with Figure 4, the vertical rod 131 is provided with a first through hole 430, the linkage rod 121 is provided with a second through hole 440, one end of the linkage plate 420 penetrates into the first through hole 430, and the other end penetrates into the second through hole 440. Specifically, one end of the linkage plate 420 penetrates into the first through hole 430 of the vertical rod 131, and the other end of the linkage plate 420 penetrates into the second through hole 440 of the linkage rod 121. When the vertical rod 131 drives the linkage plate 420 to reciprocate, because the spacing between the rotation center of the linkage plate 420 and the first through hole 430 and the second through hole 440 changes, at this time, the two ends of the linkage plate 420 can slide back and forth relative to the first through hole 430 and the second through hole 440, respectively, thereby improving the structural reliability. It should be noted that the sizes of the first through hole 430 and the second through hole 440 are slightly larger than the ends of the linkage plate 420 , so as to facilitate the movement of the linkage plate 420 and reduce the shaking of the vertical rod 131 , the linkage rod 121 and the linkage plate 420 .

[0049] Furthermore, in the present embodiment, the upper side and the lower side of the door panel 110 can be movably provided with the linkage rod 121, and the linkage rod 121 on the upper side and the linkage rod 121 on the lower side are both provided with the first lock pin 122 or the first card slot 210, and the positions corresponding to the upper side and the lower side on the cabinet body 100 are both provided with the first card slot 210 or the first lock pin 122; the linkage rod 121 on the upper side and the linkage rod 121 on the lower side are both connected with the door lock 130, and the movement of the door lock 130 drives the linkage rod 121 on the upper side and the linkage rod 121 on the lower side to move synchronously.

[0050] Specifically, the movement of the door lock 130 drives the second side 112, the upper side and the lower side of the door panel 110 to be locked or unlocked at the same time, thereby improving efficiency and being convenient and quick.
